Xcode "compact unwind" warnings

Xcode "compact unwind" warnings

When using IPP with Xcode 4 on OS X I get hundreds of warnings along the lines of:ld: warning: could not create compact unwindA KB article from 18 months ago said that an Apple update was expected to fix this. Has there been any progress on that, or is there any way to suppress those warning messages? There are so many of them that true warnings may be getting lost once the maximum number of warnings has been reached.

Using Xcode 4.3.2 on Lion (Mac OS X 10.7.3) adding -Wl,-no_compact_unwind to "Other Linker Flags" removes that warning, but it sprays a bunch of other warnings instead:

ld: warning: direct access in __ZN3UMC20ColorSpaceConversion8GetFrameEPNS_9MediaDataES2_ to global weak symbol __ZN3UMC9VideoData12GetClassNameEv means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings.
